Students must calculate the distance an object will move up an incline using Newton's Laws. Mass, angle, gravitational field, coefficient of friction and initial speed will be generated randomly.

Students must calculate the speed of a block when it returns to its original location on an incline using Newton's Laws. Mass, angle, gravitational field, coefficient of friction and initial speed will be generated randomly.

Explore sports science and see how many points can you score with your bottle caps in Ruff's take on table hockey.

Students will have an opportunity to determine what makes everyday objects move. Students will be given objects and asked to make predictions on how far each object will move after they blow on it. Then they will measure the distance and...

This interesting and interactive exhibit demonstrates how Newton's Laws of Motion impact the design and safety of roller coasters.

What is friction? Illustrated discussion of friction including the three types, its importance, and why it is avoided.

This lesson introduces the concept of static friction and explains how it depends on the surface an object is resting on. It is 2 of 2 in the series titled "Static Friction Revisited."

Kids learn about the science behind friction including how it works as a force to slow things down, how it helps us stand, preventing friction, types, and fun facts.

What is force? Illustrated discussion of how force is calculated and three familiar types.

[Free Registration/Login Required] In this unit children build on their existing knowledge of forces and learn that forces can be measured and compared. The unit focuses on friction.

Students must determine the work done by a force on an angle when there is no friction present between the box and the table. Students must also find the final speed of the box after this work has been added to the box.

Students must determine the amount of work that is done by tension and the amount of work done by friction. Then students must find the work that turned into KE.

This lab was designed to have students look at the factors that might affect the angle at which an object will start to move when it is placed on an inclined plane. The friction coefficient of the surfaces, the strength of the...

The intricate relationship between work and mechanical energy is depicted in the animation for students to be able to visualize.
